Lettelrs Patent No. 93,485, dated August l0, 1869.

IMPROVED MECHANICAL MvEMEN-i'.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern y Be it known that I, HENRY F. SHAW, of West Roxbury, in the county of Norfolk, and State of Massachusetts, have invented a certain new and useful Mechanical Movement; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

` rIhe nature of my invention consists in combining a a series of cams attached to asingle shaft, with a series of luted wheels, also attachedto a single shaft, the cams so set in relation to the lted wheels that the action of the cams'is successive, one no sooner ceases to hear than another comes into action; by which dei vice I am enabled to produce a continuous action of A is a shaft propelled by a crank, or by anydesirable On this shaft, a series of cams or eccentrics, C C C",

. is made fast.

These cams are set so that the angles made by the longer diameters each to each shall be equal, that is, withthree ccams the diameter will make angles vof one hundred and twentydegrees, or cue-third of a circle each. With four cams, the diametric angles will be each ninety degrees, Ste.

v E represents the shaft to which the fluted wheels D D' D are attached, these fluted' wheels being, in humber, equal tothe cams, and are set in relation t'o each other,fso that their corrugat'i'ons will.be acted upon successively by the cams C O C".

In fig. 2, I have shown my device as it would appear on a lifting-jack.`

XVhat I claimas my invention, and desire to secure by Letters Patent of theUnited States, is-` As a new mechanical movement, the series of cams C G C, actuating a'correspouding uted bar or compound wheel, substantially as .described and for the purpose set forth.

HENRY F. SHAW.
